TECHNICAL FIELD

The present disclosure relates to a screen display technique. More particularly, the present disclosure relates to a user interface (UI) display method and apparatus.

BACKGROUND

Recently, with the rapid development of electronic technologies, functions of electronic devices, such as computers, laptop computers, tablet personal computers (PCs), navigation systems, smartphones, cellular phones, and so forth, have been diversified, and the currently released electronic devices offer various user interfaces (UIs) for user convenience. A UI may perform prompt and intuitive information delivery through simple manipulation. Thus, to allow users to conveniently use electronic devices, UI-related techniques have been actively developed.

Among UI techniques of the related art, a UI display-related technique includes displaying a manipulation unit on an entire screen or a partial screen once a user pops up the manipulation unit necessary for a work environment.

In addition, Korean Patent Publication No. 2010-0041444 (Title: Method and Apparatus for Displaying Transparent Pop-up Including Additional Information Corresponding to Information Selected on Touchscreen, Inventor: Tae-Kyun Cho, Applicant: Samsung Electronics Co., Ltd., Publication Date: Nov. 9, 2011) is a technique related to UI display according to the related art, which discloses a technique for displaying a transparent pop-up including additional information corresponding to information located in the same area as the displayed pop-up without closing the displayed pop-up.

FIGS. 1A and 1B illustrate UI display operations according to the related art and FIG. 2 illustrates a UI display operation according to the related art.

Referring to FIGS. 1A, 1B and 2 , a UI display technique of the related art provides a screen for manipulation by a user as an entire screen or a partial screen, and the user has to close or move the provided manipulation screen to check data below the manipulation screen. For example, if the user desires to manipulate a brightness of a screen by pulling down a notification bar on the home screen as shown in FIGS. 1A and 1B, the user may not check the home screen having the actually set brightness and thus may have to adjust the brightness again. Also, as shown in FIG. 2 , if a pop-up menu is generated to change attributes of a square, the square is entirely or partially occluded, such that an additional operation of moving the pop-up menu is needed to check if a desired color is correctly reflected.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

SUMMARY

Aspects of the present disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a user interface (UI) display method and apparatus for minimizing a part occluded by an operation window when a user pops up the operation window on a screen. Thus, when the user pops up a window for an additional operation on a work screen, the user may perform a desired operation without taking additional trouble to move the additional operation window and may immediately check the screen to which the operation is reflected.

In accordance with an aspect of the present disclosure, a UI display method is provided. The UI display method includes displaying an operation window including one or more setting items on a screen and, if an input is generated on a first item among the one or more setting items of the operation window displayed on the screen, causing at least a part or all of a remaining part of the operation window except for the first item not to be displayed on the screen.

In accordance with another aspect of the present disclosure, a UI display apparatus is provided. The UI display apparatus includes an input unit configured to receive a user's operation, a display unit configured to display an execution image and an operation state and a menu state of an application, and a controller configured to display an operation window including one or more setting items on the display unit, and if an input is generated on a first item among the one or more setting items of the operation window displayed on the display unit according to an input through the input unit, to control at least a part or all of a remaining part of the operation window except for the first item not to be displayed on the display unit.

As described above, by using a UI display method and apparatus according to the present disclosure, when a user pops up a screen for an operation on a screen, a part occluded by the operation screen may be minimized. Thus, an additional operation of the user, such as moving a popup menu to prevent the popup menu from occluding a picture below the popup menu, may not be necessary. Moreover, an operation and a screen to which the operation is actually applied may be immediately checked.

The microphone 162 receives a voice or sound and generates a corresponding electric signal under control of the controller 110.

The speaker 163 may include a plurality of speakers and be formed in one or more positions of the portable terminal device 100. The speaker 163 outputs a sound corresponding to various signals (for example, wireless data, broadcast data, a digital audio file, a digital video file, a picture, or the like) of the mobile communication module 120, the sub communication module 130, the multimedia module 140, or the camera module 150 under control of the controller 110. The speaker 163 may output sound corresponding to a function executed by the portable terminal device 100 (for example, button manipulation sound corresponding to a phone call, or a ring back tone).

The vibration motor 164 converts an electric signal into mechanical vibration under control of the controller 110. For example, in the portable terminal device 100, in a vibration mode, if a voice call from another device (not shown) is received, the vibration motor 164 operates. One or more of the vibration element 164 may be disposed in the housing of the portable terminal device 100. The vibration element 164 may operate in response to a user's touch action of touching the touch screen 190 and a continuous movement of a touch on the touch screen 190.

The connector 165 may be used as an interface for connecting the portable terminal device 100 with an external device (not shown) or a power source (not shown). Under control of the controller 110, the portable terminal device 100 transmits data stored in the storing module 175 of the portable terminal device 100 to an external device (not shown) or receives data from the external device through a wired cable connected to the connector 165. The portable terminal device 100 receives power from the power source (not shown) through the wired cable connected to the connector 165 or charges a battery (not shown) by using the power source.

The keypad 166 receives key input from the user for control of the portable terminal device 100. The keypad 166 includes a physical keypad (not shown) formed in the portable terminal device 100 or a virtual keypad (not shown) displayed on the touch screen 190. The physical keypad (not shown) formed in the portable terminal device 100 may be excluded according to the capability or structure of the portable terminal device 100.

An earphone (not shown) may be inserted into the earphone connecting jack 167 to be connected to the portable terminal device 100.

The touch screen 190 receives a user's manipulation and displays an execution image of an application program and an operation state and a menu state. That is, the touch screen 190 provides a UI corresponding to various services (for example, call, data transmission, broadcasting, picture taking) to the user. The touch screen 190 transmits an analog signal corresponding to at least one touch input into the UI to the touch screen controller 195. The touch screen 190 receives at least one touch input through a user's body (for example, a finger including a thumb) or a touchable input means (for example, a stylus pen). The touch screen 190 receives a continuous movement of at least one touch. The touch screen 190 delivers an analog signal corresponding to the received continuous movement of the touch to the touch screen controller 195.

In an embodiment of the present disclosure, a touch is not limited to a direct contact between the touch screen 190 and a user's body or a touchable input means, and may also include a non-contact touch. A detectable interval from the touch screen 190 may be changed according to the capability or structure of the portable terminal device 100. For example, to separately detect a direct touch event based on a contact with the user input means and non-contact touch event (for example, a hovering event), the touch screen 190 may be configured to output different values (for example, current values) for the touch event and for the hovering event. The touch screen 190 may preferably output different detected values (for example, current values) according to a distance between a space where the hovering event occurs and the touch screen 190.

The touch screen 190 may be implemented, for example, as a resistive type, a capacitive type, an electro-magnetic resonance (EMR) type, an infrared type, or an acoustic wave type.

The touch screen controller 195 converts an analog signal received from the touch screen 190 to a digital signal (for example, X and Y coordinates) and delivers the digital signal to the controller 110. The controller 110 may control the touch screen 190 using the digital signal received from the touch screen controller 195. For example, the controller 110 may control selection or execution of a shortcut icon (or an application corresponding thereto) displayed on the touch screen 190 in response to a touch event or a hovering event. The touch screen controller 195 may be incorporated into the controller 110.

The touch screen controller 195 detects a value (for example, a current value) output through the touch screen 190, identifies a distance between the space where the hovering event occurs and the touch screen 190, converts the identified distance into a digital signal (for example, a Z coordinate), and provides the digital signal to the controller 110.

The touch screen 190 may include at least two touch panels capable of sensing a touch or proximity of the user's body and the touchable input means to simultaneously receive inputs by the user's body and the touchable input means. The at least two touch panels provide different output values to the touch screen controller 195. Thus, the touch screen controller 195 differently recognizes the values input from the at least two touch screen panels to identify whether the input from the touch screen 190 is the input generated by the user's body or the touchable input means.

The storing module 175 stores a signal or data which is input/output to/from the mobile communication module 120, the sub communication module 130, the multimedia module 140, the camera module 150, the GPS module 155, the input/output module 160, the sensor module 170, or the touch screen 190, under control of the controller 110. The storing module 175 may also store a control program and applications for control of the portable terminal device 100 and/or the controller 110.

The term “storing module” includes the storing module 175, a read only memory (ROM) 112 and a random access memory (RAM) 113 in the controller 110, or a memory card (not shown) mounted in the portable terminal device 100 (for example, a secure digital (SD) card, a memory stick). The storing module may include a non-volatile memory, a volatile memory, a hard disk drive (HDD), or a solid state drive (SSD).

The controller 110 includes a central processing unit (CPU) 111, the ROM 112 in which a control program for controlling the portable terminal device 100 is stored, and the RAM 113 which stores a signal or data input from the portable terminal device 100 or is used as a memory region for a task performed in the portable terminal device 100. The CPU 111 may include a single core, a dual core, a triple core, or a quad core processor. The CPU 111, the ROM 112, and the RAM 113 may be interconnected through an internal bus.

The controller 110 controls the mobile communication module 120, the sub communication module 130, the multimedia module 140, the camera module 150, the GPS module 155, the input/output module 160, the sensor module 170, the storing module 175, the power supply module 180, the touch screen 190, and the touch screen controller 195.

According to characteristics of a UI display operation of the present disclosure, the controller 110 may control at least a part or all of the remaining operation window part except for a first item on an operation window displayed on the touch screen 190 not to be displayed on the touch screen 190, if an input is generated onto the first item among one or more setting items of the operation window displayed on the touch screen 190 due to an input through the touch screen 190. If the input to the first item is ended after the controller 110 controls at least a part or all of the remaining operation window part except for the first item on the operation window displayed on the touch screen 190 not to be displayed on the touch screen 190, the controller 110 controls the at least a part or all of the remaining operation window part except for the first item on the operation window displayed on the touch screen 190 to be displayed on the touch screen 190 again.

FIG. 4 is a flowchart of a UI display operation according to an embodiment of the present disclosure.

Referring to FIG. 4 , if an input is generated in a part the user actually operates after an operation window is displayed on the screen, the remaining operation window part except for the part where the input is generated disappears from the screen. Moreover, if the user's input is terminated (if the focus is off for selection completion or another operation), an initially provided operation window is restored on the screen. Thus, the illustrated example provides the operation window the user may change and the screen onto which an operation is to be reflected at the same time.

In operation 201, an operation part is executed by a user's manipulation or operation such as a voice input, a touch, a pressing of a button, or the like, and in operation 203, a window of the executed operation is displayed on the screen. The operation part may be, for example, an environment setting or a notification bar of a portable terminal device, and the operation window may include one or more setting items. The setting items may include various items, for example, a screen brightness setting, a font size setting, a volume setting, and so forth. The window operation displayed on the screen may be displayed as the entire screen or a partial screen of the portable terminal device.

In operation 205, it is determined whether an input is generated on a first item among the one or more setting items of the operation window. The input may include a pressing of a button, a touch, a hovering input, a voice input, etc. to activate the first item.

If it is determined in operation 205 that the input is generated on the first item of the operation window, the process goes to operation 207. Otherwise, if it is determined that the input is not generated on the first item of the operation window, operations are terminated.

In operation 207, the remaining part of the operation window except for the operation window is caused not to be displayed on the screen. This is intended to display only the first item on the screen by changing a screen setting in such a way so as not to display the remaining part of the operation window except for the first item, if an input is generated in a part the user actually manipulates.

In operation 209, it is determined whether a screen setting has changed by the input generated on the first item of the operation window. If it is determined in operation 209 that the screen setting has changed by the input generated on the first item of the operation window, the process goes to operation 211. Otherwise, if it is determined in operation 209 that the screen setting has not changed by the input generated on the first item of the operation window, the process goes to operation 213.

In operation 211, the setting change is applied to the screen.

In operation 213, it is determined whether the input of the first item is terminated. The input termination may correspond to a case where setting of the first item has completed by selection of an end button or a cancel button, or selection of a back button. The input termination may be input termination corresponding to the elapse of a preset time or generation of an input in a part other than the first item. If it is determined in operation 213 that the input of the first item is terminated, the process goes to operation 215, and if it is determined in operation 213 that the input of the first item is not terminated, the process goes back to operation 207.

In operation 215, the remaining part of the operation window except for the first item is caused to be displayed on the screen again. This operation restores the operation window.

FIGS. 5A to 5D illustrate UI displays corresponding to a hand touch according to an embodiment of the present disclosure.

Referring to FIGS. 5A to 5D, when an operation window is displayed as the entire screen on a home screen, upon a touch input onto a scroll bar for adjusting screen brightness as shown in FIG. 5A, the remaining part of the operation window except for the scroll bar disappears from the screen as shown in FIG. 5B, displaying only the scroll bar on the home screen. In this state, if a point of the scroll bar is moved through the touch and/or the drag, the screen brightness is changed and applied according to a position of the point of the scroll bar as shown in FIG. 5C. Once the touch is removed from the scroll bar, the operation is restored on the home screen as shown in FIG. 5D.

According to another embodiment of the present disclosure, an operation part in a desktop or laptop computer may be a setting menu including setting items such as background setting, resolution setting, and so forth or an edit menu for a document, an image, and so forth. An input generated in a first item, which is one or more setting items of the operation window, may include a mouse over, a mouse click, a mouse drag, or the like.

FIGS. 6A and 6B illustrate UI displays corresponding to a mouse input according to an embodiment of the present disclosure.

Referring to FIGS. 6A and 6B, a UI display operation corresponding to a mouse input will be described below. When an operation window is displayed on the screen overlappingly with an image as shown in FIG. 6A, if a mouse over occurs on a theme color item to apply a figure filling effect to the image, the remaining part of the operation window except for the theme color item disappears from the screen as shown in FIG. 6B, displaying only the theme color item on the image. Thereafter, according to the position of the point of the mouse, the color of the image is changed into a color where the mouse over is positioned. When a color is clicked by the mouse, the color is applied to the image and the theme color item disappears from the screen, displaying only the image on the screen.

FIGS. 7A and 7B illustrate UI displays corresponding to a mouse input according to another embodiment of the present disclosure.

Referring to FIGS. 7A and 7B, a UI display operation corresponding to a mouse input according to another embodiment of the present disclosure will be described below. When an operation window is displayed on the screen overlappingly with an image as shown in FIG. 7A, if a mouse over occurs on a three-dimensional (3D) rotation item to apply 3D rotation to the image, the remaining part of the operation window except for the 3D rotation item disappears from the screen as shown in FIG. 7B, displaying only the 3D rotation item on the image. Thereafter, according to the position of the mouse over, the image is rotated in a rotation direction of the rotation item where the mouse over is positioned. In this case, if one rotation item is clicked by the mouse, the image is rotated in a rotation direction of the rotation item, and the operation window as shown in FIG. 7A is displayed on the screen again.

FIGS. 8A to 8C illustrate UI displays corresponding to a hand touch according to another embodiment of the present disclosure.

Referring to FIGS. 8A to 8C, a UI display operation corresponding to a hand touch will be described below. Referring to FIG. 8A to 8C, when a screen including an indicator area 11 and a notification area 12 is displayed on the home screen as shown in FIG. 8A, an item for automatically or manually setting the screen brightness of the portable terminal device (hereinafter, referred to as an auto brightness mode on/off switch) among setting items for changing specific setting of a portable terminal device may be positioned in a preset part of the indicator area 11. The auto brightness mode on/off switch may switch on or off an auto brightness mode by a user input, for example, a sort of touch, a tap (a gesture of shortly and lightly tapping the screen with one finger).

FIG. 8A illustrates a screen on which the auto brightness mode enters an on state, and if the indicator area 11 is displayed on the screen, the auto brightness mode is automatically switched on. If the auto brightness mode is switched on as shown in FIG. 8A, the brightness of the displayed screen may be automatically adjusted to a preset value as shown in FIG. 8A.

When the auto brightness mode is switched on as shown in FIG. 8A, if a tap is input to the auto brightness mode on/off switch, the auto brightness mode may be switched off and a scroll bar for adjusting the screen brightness may be displayed as shown in FIG. 8B. If another tap is input to the auto brightness mode on/off switch in the state shown in FIG. 8B, the screen where the auto brightness mode is in the on state as shown in FIG. 8A may be displayed. Referring to FIG. 8B, to display the scroll bar for a user's manually setting the screen brightness on a preset part under the auto brightness mode on/off switch, the notification area 12 including notification items is moved down and the indicator area 11 including setting items is enlarged to display the scroll bar for manually adjusting the screen brightness in a preset part of the indicator area 11. Thereafter, once the point of the scroll bar is moved in the scroll bar for adjusting the screen brightness by a touch and/or a drag, the remaining part except for the indicator area 11 disappears from the screen as shown in FIG. 8C, thus displaying only the indicator area 11 including the setting items and the scroll bar for adjusting the screen brightness on the screen to adjust the brightness of the screen.
